Description

The present invention relates to a rhombic wire mesh, and more particularly to a composite rhombic wire mesh that is lightweight and has excellent shock absorption performance, which is formed by integrating two rhombic wire meshes in a slidable manner.

A rhombic wire mesh is a wire mesh in which corrugated wire rods are knitted together to form a continuous parallelogram mesh. Specifically, it is formed by connecting wavy wire rods extending in the X direction in the Y direction orthogonal to the X direction via upper and lower protrusions.
Diamond-shaped wire mesh has advantageous features such as excellent flexibility because the mesh joints are not fixed, easy transportation because it can be folded, and partial repair possible by replacing the wire rods. Widely used for various purposes.
For example, a fence using diamond-shaped wire mesh is constructed by stretching the diamond-shaped wire mesh between two pillars erected on the ground and fixing the top and bottom of the diamond-shaped wire mesh to the rim. A rockfall protection net using diamond-shaped wire mesh is constructed by erecting pillars at the top of a steep slope, stretching wire ropes between the pillars, and suspending the diamond-shaped wire mesh from the wire ropes like a curtain.

"JIS G3552 Diamond Wire Mesh" (Japanese Industrial Standards: 2007)

In the conventional diamond-shaped wire mesh, adjacent corrugated wire rods are engaged with each other at all intersection points, so when the wire mesh surface receives impact from falling rocks or vehicle collisions, the received energy is dispersed and absorbed. I can't. For this reason, stress concentrates on the receiving portion of the wire mesh surface, which tends to cause damage.
Furthermore, since the energy received by the wire mesh surface is directly transmitted to the fixed members such as the pillars of the fence and the fixed wires of the rockfall protection net, the fixed members are easily deformed. In particular, if the fixing member is deformed or damaged, it will take more time to repair than replacing the wire mesh surface, and the repair cost will increase.

An object of the present invention is to provide a composite diamond-shaped wire mesh for solving the above-mentioned problems.

The composite rhombic wire mesh of the present invention is a rhombic wire mesh formed by connecting a plurality of wavy row lines extending in the X direction in the Y direction orthogonal to the X direction, in which the first row of the same shape is The line and the second column line are shifted in the X direction and arranged in parallel, and each first column line has a first upper protrusion that protrudes upward in the Y direction, a first lower protrusion that protrudes downward in the Y direction, a first linear part that connects the first upper protrusion and the first lower protrusion; each second column line has a second upper protrusion that protrudes upward in the Y direction; and a first linear part that connects the first upper protrusion and the first lower protrusion; It consists of a second lower protrusion that protrudes, and a second linear part that connects the second upper protrusion and the second lower protrusion, and the first lower protrusion on the upper level is connected to the second upper protrusion on the lower level. The second lower protrusion part of the upper stage does not engage with the first upper protrusion part of the lower stage and forms a first engaging part. 2 to form a second engaging part, and the second engaging part was restrained between two adjacent first engaging parts in the X direction so as to be slidable in the X direction. It is characterized by

In the composite diamond-shaped wire mesh of the present invention, the second engaging portion may be arranged approximately at the center of two first engaging portions adjacent to each other in the X direction.

In the composite diamond-shaped wire mesh of the present invention, the color of the first row line may be different from the color of the second row line.

In the composite diamond-shaped wire mesh of the present invention, in each stage, additional column lines having the same shape as the first column line and the second column line are arranged in parallel while being shifted in the X direction, and each additional column line projects upward in the Y direction. It consists of an upper protrusion, a lower protrusion that protrudes downward in the Y direction, and a linear part that connects the upper protrusion and the lower protrusion. The engagement portion may be configured by engaging with the upper protrusion of the additional row line in the lower tier without engaging with the upper protrusion and the second upper protrusion in the lower tier.

Since the composite rhomboid wire mesh of the present invention has the above configuration, it has at least one of the following effects.
<1> Since it has a structure in which two diamond-shaped wire meshes are slidably integrated, when receiving damage from falling rocks or vehicle collisions, the sliding of the diamond-shaped wire meshes can disperse and absorb the received energy. Therefore, it has excellent shock absorption performance and the wire mesh surface is less likely to be damaged. Furthermore, by absorbing the energy received on the wire mesh surface within the wire mesh surface, it is possible to prevent deformation and damage of fence posts, fixed wires of rockfall protection nets, etc.
<2> Compared to the diamond-shaped wire mesh of the prior art, the number of engaging parts of the row lines is half for the same mesh size, so it is lightweight and highly flexible. Therefore, it is easy to transport and deploy, and has high workability.
<3> The mesh size can be arbitrarily set by changing the relative position of the two diamond-shaped wire meshes, so it is highly versatile.
<4> By changing the relative positions of the two diamond-shaped wire meshes, the mesh shape can be arbitrarily deformed, resulting in a high degree of design.

[Composite rhombus wire mesh]
<1> Overall configuration (Figures 1 and 2)
The composite diamond-shaped wire mesh 1 of the present invention is a wire mesh in which two diamond-shaped wire meshes are slidably integrated.
The composite rhombic wire mesh 1 is composed of a combination of a first rhombic wire mesh 1A and a second rhombic wire mesh 1B. Specifically, the second engaging portion 24 of the second rhombic wire mesh 1B is held within the mesh M of the first rhombic wire mesh 1A, and the second engaging portion 24 of the first rhombic wire mesh 1A is The engaging portion 14 is held and integrated. On the other hand, the intersections of the first rhombic wire mesh 1A and the second rhombic wire mesh 1B do not engage.
With this structure, the first rhombic wire mesh 1A and the second rhombic wire mesh 1B are slidably connected to each other in the X direction and the Y direction.
In this example, the second engaging portion 24 of the second rhombic wire mesh 1B is arranged at the center of the mesh of the first rhombic wire mesh 1A. By arranging them in this way, the mesh size of the mesh M can be set to 1/2 of that of the first rhombic wire mesh 1A and the second rhombic wire mesh 1B.
In this example, the first rhombic wire mesh 1A is not colored, and the second rhombic wire mesh 1B is colored black. This, combined with the unique structure, allows for a high level of design.

<2> First rhombic wire mesh (Figure 3)
The first rhombic wire mesh 1A is formed by connecting a plurality of first column lines 10 extending in the X direction in the Y direction.
In this example, the mesh size of the first rhombic wire mesh 1A is 40 mm.
The first column line 10 is made of a substantially corrugated metal wire that extends in the X direction and projects in the Y direction.
In this example, a galvanized iron wire with a wire diameter of 4.0 mm whose surface is coated with resin is used as the first row wire 10. However, the first row wire 10 is not limited to this, and any combination of wire diameter and material can be adopted.
The first column line 10 includes a first upper protrusion 11 that protrudes upward in the Y direction, a first lower protrusion 12 that protrudes downward in the Y direction, a first upper protrusion 11 and a first lower protrusion 12. and a first linear portion 13 that connects the two.
The first upper protruding part 11 and the first lower protruding part 12 of the two first row lines 10 arranged in parallel in the Y direction are engaged with each other to form a first engaging part 14 .

<3> Second rhombus wire mesh (Figure 3)
The second rhombic wire mesh 1B is formed by connecting a plurality of second row lines 20 extending in the X direction in the Y direction.
The mesh size of the second rhombic wire mesh 1B is 40 mm, which is the same as that of the first rhombic wire mesh 1A.
The second column line 20 is made of a substantially corrugated metal wire extending in the X direction and protruding in the Y direction.
In this example, a galvanized iron wire with a wire diameter of 4.0 mm whose surface is coated with resin is used as the second row wire 20. However, the second row wire 20 is not limited to this, and any combination of wire diameter and material can be adopted.
The second column line 20 includes a second upper protrusion 21 that protrudes upward in the Y direction, a second lower protrusion 22 that protrudes downward in the Y direction, a second upper protrusion 21 and a second lower protrusion 22. and a second linear portion 23 that connects the two.
The second upper protrusion 21 and the second lower protrusion 22 of the two second row lines 20 arranged in parallel in the Y direction engage with each other to form a second engaging portion 24 .

<4> Engagement structure between the first rhombic wire mesh and the second rhombic wire mesh (Figures 1 and 2)
The first rhombic wire mesh 1A and the second rhombic wire mesh 1B are slidably connected to each other.
In each stage of the composite diamond-shaped wire mesh 1, the first row line 10 and the second row line 20 are arranged in parallel with each other in a state shifted in the X direction.
The first lower protrusion 12 on the upper stage engages with the first upper protrusion 11 on the lower stage to constitute the first engaging part 14, and the second lower protrusion 22 on the upper stage engages with the first upper protrusion 11 on the lower stage. The second engaging portion 24 is engaged with the portion 21 .
On the other hand, the upper first lower protrusion 12 does not engage with the lower second upper protrusion 21, and the upper second lower protrusion 22 does not engage with the lower first upper protrusion 11. That is, the first rhombic wire mesh 1A and the second rhombic wire mesh 1B do not have an intersection (an engaging portion).
With the above structure, the first engaging portion 14 is mutually restrained within the mesh M of the second rhombic wire mesh 1B, and the second engaging portion 24 is restrained within the mesh M of the first rhombic wire mesh 1A.

<5> Deformation of mesh shape (Figures 4 to 6)
When the first rhombic wire mesh 1A and the second rhombic wire mesh 1B are slid to both sides in the X direction, the shape of the mesh M of the composite rhombic wire mesh 1 changes.
Specifically, by moving the first engaging part 14 of the first rhombic wire mesh 1A in the X-axis direction and bringing it close to the second engaging part 24 of the second rhombic wire mesh 1B, some of the meshes M are As the size decreases, the mesh size of the other meshes M increases (FIG. 4). As a result, the first linear portion 13 and the second linear portion 23 are brought close to each other, and a unique shape in which the diagonal lines are emphasized can be formed (FIGS. 5 and 6).

<6> Functions of composite rhombic wire mesh The composite rhombic wire mesh 1 connects the first engaging portion 14 (second engaging portion 24) of the first rhombic wire mesh 1A (second rhombic wire mesh 1B) to the second rhombic wire mesh 1B (second rhombic wire mesh 1B). It has a structure in which it is constrained within the mesh M of the diamond-shaped wire mesh 1A). Therefore, the two diamond-shaped wire meshes can relatively slide in both the X and Y directions.
In this example, the first engaging portion 14 of the first rhombic wire mesh 1A is arranged at the center of the mesh of the second rhombic wire mesh 1B (FIG. 4(A)).
In the case of a fence or falling rock protection net, if a falling rock or a vehicle collides with the surface of the wire mesh, the intersections of the first rhombic wire mesh 1A and the second rhombic wire mesh 1B are not engaged, so the first rhombic wire mesh 1A and the second rhombus wire mesh The wire mesh 1B slides relatively in the X direction (FIG. 4(B)). At this time, the friction between the first linear part 13 and the second linear part 23 converts the received energy into thermal energy, which can be dispersed and absorbed over the entire wire mesh surface.
Further, in the case of this example, the mesh size of the mesh M partitioned by the first rhombic wire mesh 1A and the second rhombic wire mesh 1B is 20 mm, which is half of the mesh size of 40 mm of the first rhombic wire mesh 1A. Since the intersection point and the intersection point of the second rhombic wire mesh 1B are not engaged, the number of engaging portions is half that of the 20 mm diamond wire mesh of the prior art (FIG. 4(A)).
In the technical field of wire mesh, there is a property that "small doubles as large", that is, a wire mesh with a small mesh size has the functions of a large wire mesh, but not vice versa. The weight can be reduced compared to the previous one, and the amount of iron used can be reduced, reducing raw material costs.

[Example of combination of 3 or more pieces of rhombic wire mesh]
In the first embodiment, the composite rhombic wire mesh 1 consists of two pieces, the first rhombic wire mesh 1A and the second rhombic wire mesh 1B, but the number of rhombic wire meshes is not limited to two.
For example, the composite rhombic wire mesh 1 may be composed of three pieces: a first rhombic wire mesh 1A, a second rhombic wire mesh 1B, and a third rhombic wire mesh 1C (FIG. 7(A)).
The third rhombus wire mesh 1C has the same structure as the first rhombus wire mesh 1A and the second rhombus wire mesh 1B, and is formed by connecting a plurality of additional column lines 30 extending in the X direction in the Y direction.
The additional column line 30 includes an upper protrusion 31 that protrudes upward in the Y direction, a lower protrusion 32 that protrudes downward in the Y direction, and a linear part 33 that connects the upper protrusion 31 and the lower protrusion 32. Consisting of
The third rhombic wire mesh 1C is connected to the first rhombic wire mesh 1A and the second rhombic wire mesh 1B by the same means as in the first embodiment. Specifically, in each stage of the composite diamond-shaped wire mesh 1, the additional column lines 30 are arranged in parallel and shifted from the first column line 10 and the second column line 20 in the X direction. The upper and lower additional column lines 30 engage the lower protrusion 32 of the upper tier with the upper protrusion 31 of the lower tier to form an engaging portion 34, but are not engaged with the first column line 10 and the second column line 20. It doesn't match.
Similarly, by increasing the number of additional column wires 30 per stage, the composite rhombic wire mesh 1 can be made into four pieces: the first rhombic wire mesh 1A, the second rhombic wire mesh 1B, the third rhombic wire mesh 1C, and the fourth rhombic wire mesh 1D. (FIG. 7(B)), or it can be composed of five or more sheets.
In the case of this example, by combining the color schemes of the row lines, a variety of designs can be constructed and a high aesthetic appearance can be achieved as an interior wire mesh.
